Analyzer Sampling Patents: Top Companies & Filing Trends 2026
Analyzer Sampling and Conditioning Systems Patents
One filer dominates. the leading assignee holds 160 of 246 records in scope, and the top 5 combined account for 85.8% of all filings. Filings rose from 13 in 2017 to a peak of 32 in 2018. The tracked growth span shows filings falling from 10 in 2021 to 6 in 2024, a -40% change; because publication lags filing by roughly 18 months, 2025 and 2026 figures are still incomplete and should not be read as a continued decline on their own.

Common questions on analyzer sampling patents
Who holds the most patents in analyzer sampling and conditioning systems?
One assignee holds 160 of the 246 records in scope, far ahead of the rest of the ranked field. The top 5 assignees combined account for 85.8% of all records, and the top 10 account for 94.7%. This level of concentration means most core sample-conditioning architecture is already claimed, and competitive analysis should start with that leading portfolio rather than the broader 24-company ranking.
Is patent filing in this field growing or slowing down?
Filing peaked at 32 records in 2018 and has since pulled back, falling from 10 records in 2021 to 6 in 2024, a -40% change over that span. Publication lags filing by roughly 18 months, so 2025 and 2026 figures in any dataset are still incomplete and should not be read as evidence of a continuing decline. The honest read is a cooling trend through the last complete filing year, 2024, with the very latest years still an open question.
What technology areas do these patents cover besides basic analysis?
G01N, covering material analysis and testing, appears in 90.7% of the 246 records, making it the dominant classification by a wide margin. Supporting mechanical classes include F17C for pressure vessels and gas storage at 15.0% of records and B01D for separation processes such as filtration at 8.5%. Smaller shares in classes tied to drilling, electric heating, spraying and steelmaking show where sampling technology is adapted to specific industrial settings, though these adjacent branches carry far fewer records than the core analytical claims.
Disclaimer. This analysis is based on Patsnap Eureka data drawn from a limited snapshot of global patent records and is provided for general information and reference only. Patent data carries inherent limitations — recent filings are under-counted because of publication lag, counts may be on a record or family basis, classification and applicant-name data may contain errors or duplicates, and the underlying search query defines the scope shown — so the analysis may be incomplete or inaccurate and may not reflect the full technology landscape.
Nothing here is an exhaustive prior-art, novelty, freedom-to-operate or validity search, nor does it constitute legal, financial or professional advice, and it should not be relied upon as such. Verify independently and review with qualified patent and legal professionals before acting on it.
Method: Filing trend and technology composition. Derived from a Patsnap search on Analyzer Sampling and Conditioning Systems covering 2015–2026, data cut-off 2026-07-31. Counts reflect published records only and shift as new filings publish. Every share divides by all records in scope. Data: Patsnap Eureka. See the full landscape report.
